rroxumcnnox Specification of Letters Patent. P tented Oct. 23', 1917.

7 Application fi-Ied November 26, 1915. SeriaINo. 63,384.

To all whom it may concern Be it known that I, JAMES K. LANNiNe, a citizen of the United States, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have invented an,

Improvement in Picker-Checks, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representin like parts.

Thismvention relates to picker checks. In order that the rinciple of the invention may be readily unc erstood, I have disclosed a single'embodiment thereof in the accompanying drawing, wherein Figure 1 is a front elevation of a loom' having my invention applied thereto;

Fig. 2 is an underneath plan view of a portion of the raceway of the loom and representing my invention as applied thereto;

Fig. 3 is a similar view of a modified form of my invention,

Fig. 4 is a side elevation of the construction shown in Fig. 3; and

Fig. 5 is an underneath plan view of still another form of my invention.

An important object of my invention is to provide a picker stick check constructed and arranged to hold the picker stick accurately in its outward position in contact with the point of the shuttle, so that upon the inward throw of the picker stick, the shuttle is at once thrown by the picker stick without lost motion. Other objects of the invention will be set forth more fully hereinafter. 7

My improved picker check may be applied to any type of loom having picker sticks. I have herein shown a conventional loom having a. frame 1, a race'2 and picker sticks 3. The picker sticks may berocked in any suitable manner, and to that end are herein represented as provided with shoes 4. The parts thus far shown may be of any desired or usual construction.

In that form of my invention shown in Figs. 1 and 2, I ttach preferably to the under side of the race 2 of the loom, as by pivotal bolt 4 a picker stick check herein shown as consisting of a member 5 having integral therewith arms 6-6 extending in general parallelism with the slot 7 in the race. The arms 66 are slightly inclined toward each other in the direction of outward movement of the picker stick at that side of the loom, so that as the picker" stick moves outwardly, it is brought torest at a predetermined position, as indicated in- Fig. 1'. v

The check consisting of the member 5 with its arms 6 6 may be formed of one or more pieces and may be of any suitable material. Preferably, however, itis formed of some hard wood, such, for example, as maple, and the arms 6-6 are very slightly resilient, so. that they yield outwardly-somewhat in the outward movement of the, picker stick, at that side ofthe loom. I am aware that it hasheretofore been proposed toprovide a picker or shuttle check made of general U- shaped form and of one or more piecesof metal, the wings thereof being resilient. to a considerable extent, as shown, for example, in the patent to Ayer, No. 87 2,7 7 9, December 3, 1907. In such constructions, however, the wings of such picker or shuttle checks are, however, substantially highlyresilient, and the construction and mounting of the check are relatively complicated and expensive. n

An important purpose of my invention is to provide a picker check of exceedingly simple construction, which may be readily applied to the under side or to the top side of the race of the lay without altering the construction of the loom and at very slight cost.

A picker stickin normal operation has slight lateral play, frequently about one quarter of an inch. By pivoting the picker check, as at 4*, the check is permitted to yield sufliciently to accommodate such motion. Preferably also I provide lateral stops 4 secured to the race of the lay and herein shown as having adjusting screws 4 to limit the pivotal movement of the picker ck- In Figs. 3 and 4, I have shown another form of my invention. Therein I have substantially reversed the construction shown in Figs. 1 and 2 and have provided a picker stick check composed of a member 8 which is secured by pivotal bolt 9 to the outer end of the raceway of the loom or to an extension thereon. I have herein represented the race as having secured to its under side at its outer end a forked extension 10 to which the said check 8 is secured by the pivotal bolt 9 so as to lie in general parallelism therewith and preferably at the upper side thereof, as shown most clearly in Fig. 4. The said picker stick check is provided with arms 1111, preferably but not necessarily integral with the member 8 and slightly resilient. The said check may be formed of any suitable material, but preferably is formed of wood. I have herein represented the inner ends of the arms 11 as slightly beveled or flaring at the points 12, 13. The arms 1111 very slightly approach each other in the direction of inward movement of the picker stick 3.

In this form of my invention I have represented means for limiting the pivotal movement of the check the same here consisting of a transverse slot 13 which receives a pin 13" upon the bracket 10.

In Fi 5, I have shown still another form of my invention. Therein, instead of pro viding a picker check formed of a single piece of material, I provide two members 14:, 15 secured by pivotal bolts 16, 17 to the under side or to the upper side of the race of the loom, as for example, in the manner shown in Fig. 1. The said members 14, 15 have extensions or arms 18, 19 similarin construction and function to the arms 66 shown in Fig. 2, and hence needing no further description. I preferably provide limiting means, here consisting of steps 20 pro vided with adjusting screws 21. If desired, I may connect the arms 18, 19 by a yoke or in other suitable manner to compel unison movement.

It will be evident from the foregoing description that the picker stick check is of exceedingly simple construction and inexpensive. It may be applied to substantially any type of loom without substantial alteration thereof, and in practice effectively checks or holds the picker stick at a predetermined point, thus insuring contact of the picker stick and shuttle at the limit of outward throw of the shuttle.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.

Claims:

1. In a loom, a lay, a picker stick, and a frictionally acting picker check therefor consisting of slightly resilient members extending in substantial parallelism with the walls of the picker stick slot and rigidly connected together, and conjointly laterally movable to accommodate themselves to the movement of the stick.

2. In a loom, a lay, .a picker stick and a frictionally acting picker check therefor, consisting of means pivoted to a face of the lay and having slightly resilient arms extending in substantial parallelism with the walls of the picker stick slot, said arms being rigidly connected together and conjointly movable in the same direction to accommodate themselves to the movement in either direction of the picker stick.

3. In a loom, a lay, a picker stick and a frictionally acting picker check therefor consisting of two slightly resilient arms having a common pivot and extending in general parallelism with the walls of the picker stick slot, said arms being rigidly connected together and conjointly movable laterally in the same direction to accommodate themselves to the lateral movement of the picker stick.

In a loom, a lay, and a picker stick therefor, consisting of a member having a pivot and two longitudinally extending, slightly resilient arms extending in general parallelism to the slot of the picker stick, together with means to limit the lateral movement of the arms in either direction.

In a loom, a lay, a picker stick and a frictionally acting picker check therefor, consisting of two slightly resilient arms ex tending longitudinally of and inwardly overlapping the slot of the picker stick for the greater part of their length, said arms being laterally movable, and means engage,- able with said longitudinally extending arms relatively remote from the ends of said slot to limit lateral movement thereof.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
